Abstract Objective： To investigate the effect of selective alpha 1 adrenoceptor blockers on early urination of patients after transurethral electrovaporization of the prostate. Method： According to inclusion and exclusion criteria， 130 patients were selected and randomly divided into two groups， control group was given conventional treatment measures，research group was treated with conventional measures and selective alpha blocker， compared two groups’ objective index case（ postoperative maximum urine flow），（ IPSS score） and the clinical adverse reaction. Result： There were maximal urinary flow in the research group patients after treatment，（ 15.6±1.23）mL/s， IPSS score of（ 7.35±3.34） was improved significantly than the control group， the difference was statistically significant（ P<0.05）. The control group’s total adverse reaction was 38.4%， which was higher than 15.3% of the research group， the difference was statistically significant （P<0.05）. Conclusion： Selective alpha 1 adrenoceptor blocker has good clinical effect on early urination of patients after transurethral electrovaporization of the prostate it not only can effectively shorten the patients emiction time， but also avoid to severe disease， significantly improves the treatment efficiency， so it is worthy of clinical use.
